I need to be able to reset i.MX 8M MINI DEV board using external digital signal the same way as the reset button resets it.
1. Can I solder to TP407 pad and use it for resetting purpose?
2. If yes, where is this TP407 pad?
I have looked for it on the board, but could not find it.
I know I should use one of desing board files to identify its location, but I would also like to avoid installing software only for this purpose. Can anyone help please?
Hi Piotr Budzyński,
On our i.MX8M MINI EVK board, I didn't find TP407 you mentioned. But if you want to reach RESET purpose, you can do like this:
1. Reset CPU through PMIC
2. RESET CPU through JTAG Hearder
3. Warm reset CPU
If system is not in suspend mode, you can reset CPU via POR_B directly.
Hope above advice is helpful to you.
Have a nice day!
